1. Destructive Powers of Water in Poland

2. Floods in Poland
Floods are quite frequent in Poland, also in our city Gdańsk. The most dangerous floods were in 1997 and in Then many people lost their cars, houses and their lives’ work. The residents of Wrocław and Opole suffered the most in In 2010 the residents of Cracow and Sandomierz suffered the most. The reasons for the floods are different: heavy downpour, badly designed irrigation systems, melting of the snow in the mountains, too much built-in areas in towns and too little parks there.

3. Droughts in Poland
Droughts as well as floods are among the most popular natural disasters in Poland. The reasons of droughts are: too little rain accompanied by high temperatures but also too few trees and shrubs. Droughts affect bigger areas than floods. They cause huge losses in agriculture.
At the beginning of the XVIII century there was a huge drought in Poland. There were also some droughts in 1894, 1942, 1921.

4. Dehydration of a human body - What is it?
Water makes up at least two-thirds of the human body. It plays a large part in your normal functions, such as lubricating your joints and eyes, keeping your skin healthy by eliminating toxins, and facilitating proper digestion. Once the water in your body is reduced, it needs to be replaced because an imbalance between the salts and sugar in your body can affect the way you will perform.
If your body has lost one to two percent of its entire water content, you will feel thirsty, a sign that you need to replenish the lost liquids.
Dehydration happens when you've lost too much water in your body without replacing it, preventing your body to perform its normal functions. Mild dehydration can easily be treated but if it reaches extreme levels, it can be life-threatening and will require immediate medical attention.

6. Acid rains and their impact
In Poland we have acid rains, but not as often as 40 years ago. But, what are acid rains? We have two kinds of acid rains: - Sulfuric acid - H2SO4. - Nitric acid - HNO3. It comes from cars or agriculture. What's the impact of acid rains? - destruction of plants; - soil acidification
- destruction of buildings; - bad influence on animals and people

7. System of alerts for people: flood
Flood is a very dangerous natural disaster and that is why in every city there should be a flood alert “installed” but only when the city is near any rivers or seas.
Flood alert is announced when the level of water is above standard level. It is broadcast by local government. The local government look after all people and buildings.
You have to remember:
Never disregard WATER
